kilohertz to hertz table
| kilohertz (kHz) | hertz (Hz) |
|---|---|
| 0.5 | 500 |
| 1 | 1000 |
| 2 | 2000 |
| 5 | 5000 |
| 10 | 10000 |

Formula
hertz = kilohertz × 1000.
Example
10 kilohertz = 10000 hertz.
What is a kilohertz?
A kilohertz (kHz) is 1,000 Hz.
What is a hertz?
The hertz (Hz) is one cycle per second, the SI unit of frequency.
Real-world reference points
Mains power hums at 50/60 Hz; concert pitch A is 440 Hz; CPUs run in the GHz range.
| Reference | kilohertz | hertz |
|---|---|---|
| Mains electricity (50 Hz regions) | 0.05 kHz | 50 Hz |
| Concert pitch A4 | 0.44 kHz | 440 Hz |
| FM radio (~100 MHz) | 100,000 kHz | 100,000,000 Hz |
| Modern CPU (3.5 GHz) | 3,500,000 kHz | 3,500,000,000 Hz |
Mistakes to avoid with frequency conversions
- Confusing MHz with Mbps — clock frequency and data throughput are different things.
- Assuming higher GHz always means faster: per-clock work and core counts matter as much.
- Mixing 50 Hz and 60 Hz appliance ratings across regions — motors and clocks care.
